@rneedham1 You sure have a host of symptoms. You will need a really good diagnostician to add them all up and come up with an answer. I know before I was diagnosed with diabetes I would have this:
"-Shakiness, dizziness, sweating, weakness, light headedness whenever I start to feel hungry"
I think that being cold can also be a diabetes symptom but I think that must be something that your doctor would have tested for so presumably your sugars numbers are OK.
I have hypothyroidism but don't really remember what my symptoms were except feeling tired a lot and lacking energy. Many of your other symptoms also sound like they could be thyroid-related. If your doctor thinks you are fine then you can accept that for now but keep a diary of your symptoms so you can have a very specific list of symptoms and when they occurred. The other option is to get a second opinion. If you feel very strongly that your thyroid is having a problem then I would do that. I have had times when I went through a period of being somewhat hyper and I had my endocrinologist order some tests but the numbers were fine. Apparently it was something else in my life that was causing that. Right now I am going through the opposite, I am always tired, but I don't think it's my thyroid. I am thinking it may just be the winter doldrums.
